SMW creates OWL/RDF export dynamically upon request. It persists data in 
MySQL. We did some performance measures with the old (SMW1.0) store and found 
that it already did quite well compared to various RDF stores [1]. Of course, 
there is only a limited amount of insight you can get from such a small 
evaluation. 

Currently you can also use RAP in conjunction with SMW, and there might be 
further bindings to Java stores soon. Of course it is Java (unavailable on 
many servers) and hence would be an optional extension and not a replacement 
for the default MySQL store. Also RAP serves only the purpose to provide 
additional (e.g. SPARQL) interfaces to SMW, but not as a replacement backend, 
possibly even with write option.
